Question

- State Newton's second law of motion. Using this, show that no force is required for an object
moving with constant velocity.
​

Answer 1

Newton's second law of motion states that:
The rate of change of momentum of a body is directly proportional to the force applied on it and the change in momentum takes place in the direction in which the force is applied.

A body is to be moved with a constant velocity. So, its velocity should not change.
When velocity does not change, acceleration is zero.
Now, according to Newton's second law, F = ma
If there is no acceleration, then there is no force required, F = m×0 = 0
Hence, no force is required to move an object with constant velocity.

Answer 2

Answer:

The rate of change of momentum of a

body is directly proportional to the force

applied on it and change in momentum

takes place in the direction in which

the force applied.
